چکیده
This paper proposed a new topology of symmetric single-phase multilevel inverter with the smaller number semiconductor switches and optimized low-frequency control methods to optimize Total Harmonic Distortion. A nine-level single phase output is obtained by eight active switches, four diodes capacitors from two asymmetrical dc sources. The selected harmonic order in voltage eliminated PWM (SHE-PWM) based on selective elimination. To switching angles, an ant colony optimization introduced. SHE-PWM are implemented tested for THD SIMULINK platform. approach offers less best suited high-power applications medium voltage.
